That said, BB10 doesn't really offer anything compelling above Android for manufactures, and additional hardware isn't going to massively change their market share. BB customers have never been driven by cutting edge phones. Their application marketplace is so bad that there's no reason for general consumers to want to buy into the platform.
They definitely wouldn't survive a transition to a software company.
Going private may enable them to continue to do this; any purchaser that makes sense (Microsoft) would be buying their customer list and the BBM brand. Dell buying them would be a Palm goes to HP level farce.
